DEMOUNTABLE RIM.

To all to 71m z't may concern Be it known that I, FRED A. LANE, citizen ot the United States, residing at Shelburn, in thecounty of Sullivan and State of Indiana. have invented certain new and usetul Improvements in Demountable Rims, ot which the tollowing is a specification.-

This invention relates to demountable rims tor vehicle wheels.

The principal object of the invention is to produce a simplified structure which permits a quick change of the tire, thereby greatly saving both time and labor involved in this work.

A coordinate object ot the invention is to provide an efiicient device which is practical in every detail and is adaptable tor use with standard wheels and tires.

A further object consists in the use of a single locking means for the tire carrying rim, whereby release of this single means permits immediate removal otthe tire rim.

The above and other objects of this invention will be in part described and in part understood from the following description of the present preterred embodiment of the invention, wherein:

Fig. 1, is a side elevational view of a wheel telly embodying a demountable rim structure made in accordance with my invention.

Fig. 2, is a fragmentary detail vertical sectional view of the wheel telly and associated rims showing to advantage the tire valve opening. I

Fig. 3, is a plan view of the telly rim.

Fig. 4, is a cross sectional view ot the tire rim, showing to advantage the looking lugs.

Fig. 5, is a transverse sectional view of the telly, telly rim and tire rim showing the locking wedge associated therewith, the latter being shown in side elevation. and

Fig. 6, is a similar view taken through the tire valve opening.

In the drawings a telly 7 of conventional type is illustrated which is provided with a tire valve opening 8.

A telly rim 9 is mounted upon the outer periphery of said telly 7 and is fixedly secured thereto. The inner margin of said rim is bent upwardly to provide a'tlange 1t A portion of the front margin of said rim is extended as indicated at 11 and curled upwardly to provide a locking lip as indicated at 12 and shown to advantage in Figs. 1 and Specification of Letters Patent. Patented M Application filed July 13, 1920. Serial No. 395,825.

3. It will be noted that the opposite ends of i the lip gradually taper and issue into the telly rim. The widest portion of said lip is preferably arranged coincident with a line drawn transversely across the telly intersecting the valve opening 8. Upon reference to Fig. 6 ot the drawings it will be noted that the lip 12 lies parallel with the flange .10.

A plate 13 is fixedly secured to the outer periphery of said telly rim and is provided with an opening 14 which registers with the opening 8 in the telly 7. Additional plates 15 are arranged at intervals on said telly rim and serve as spacers in a manner which will be subsequently obvious.

A tire rim 16 of substantially conventional design is used which is provided with a tire valve opening 17 aligning with the openings 8 and 14 in the telly and telly rim respectively. Locking lugs 18 are arranged on opposite sides of the opening 17 and appreciably spaced therefrom. These lugs are adapted for snug engagement with the terminals ot the plate 13 when the tire rim is slipped upon the telly rim. In this way relative circumferential movement of said rims will be prevented.

To retain the tire rim on the telly rim :1 locking wedge 19 is provided, the wedge shaped end of which is interposed between the tire rim and tellv rim; A bolt 20 extends through the telly 7 adjacent the telly rim and passes through a wear plate 21 which is secured to the outer tace ot the telly. The bolt continues through said plate 21 and engages thewedge shaped lock 19, the bolt being held in the usual way by a nut 22.

In use of the device, the tire rim is first engaged with the telly by inserting the tire valve through the openings 1d, 17, and 8. The tire and rim are permitted to gravitate downwardly until the upper inner periphery of the tire rim engages the upper outer periphery ot the telly rim. At this point lateral displacement of the tire rim will be pre vented because ot the flange 10 on one side and the locking lip 12 on the opposite side. The locking wedge 19 is arranged on the telly 7 at a point diametrically opposite to the locking lip 12, thereby preventing accidental displacement of the tire rim trom the telly rim at any point on the latter. However, it is understood that when the tire is to be removed it isnecessary to disengage only the single nut 22, permitting Withdrawal of the locking wedge 19, thereby permitting the tire and tire rim to be slipped from the felly rim at this point, pursuant to which pressure is exerted upon the tire to force the same beyond the upper margin of the flange 10 and lip 12, permitting the tire valve to be withdrawn through the valve openings.

It will be obvious therefore that thetire rim is locked in place by the use of a single nut and-bolt, and consequently removal'of the tire is permitted by the removal of only the i one nut thereby greatly expediting changing tires. i

It is to be understood that I have above described only the preferred form of my invention and'changes may be made therein by me within the scope of the appended claims.

What I claim is, V In combination with a wheel felly having a valve stem opening, and rim mounted on said felly, one margin of which is flanged FRED A. LANE.
